The controlling provision is section 333E of the Fair Work Act 2009 (Cth), inserted by the Fair Work Legislation Amendment (Secure Jobs, Better Pay) Act 2022 and in force since 6 December 2023. It imposes three hard limitations on any fixed-term or maximum-term contract entered into after that date. First, the contract cannot run for longer than two years, counting the original term plus any extension or renewal. Second, it cannot provide for more than one extension or renewal. Third, it cannot be used to string together consecutive contracts for the same or substantially similar work where there is continuity of employment and the total exceeds two years or involves more than one renewal. These are civil remedy provisions, so getting them wrong is not a technicality: penalties can be imposed on both the company and the individuals involved.
The consequence of breach is unusual and worth understanding. Under the Act, if a contract falls foul of s.333E, the offending end-date term simply has no effect, while the rest of the contract survives. The practical result is that your "fixed-term" employee quietly becomes an ongoing employee, with all the notice, redundancy and unfair-dismissal exposure that follows. You do not get to argue the contract ended on schedule, because the schedule was never valid.
Section 333F carves out the exceptions where the limitations do not apply. The most commonly relied on are the high-income exception (earnings above the threshold, which is $190,100 from 1 July 2026), genuine specialised-skills project work, training arrangements, temporary replacement of an absent employee, essential work during peak demand, and roles funded by government grants payable for more than two years with no reasonable prospect of renewal. Casual employees fall outside the regime entirely. Separately, section 333L requires you to give every new fixed-term employee the Fixed Term Contract Information Statement (FTCIS) issued by the Fair Work Ombudsman, alongside the standard Fair Work Information Statement, at the time the contract is entered into. The current version and full guidance sit on the Fair Work Ombudsman guidance on fixed term contract employees, which is the authoritative reference for the exceptions and the threshold calculations.
